1. Check the symlink exists: assuming the switches are the same as linux, you can look with ls -l ~/bin2. It exists, then Is the symlink executable?3. If yes, try to run subl with a pathref: ~/bin/subl. No? chmod +x to make executable. 4. If it runs with pathref, is ~/bin in the path? probably is but I don't know with Macs (should be)
